2 Claims. (Cl. 56-377) This invention relates to an implement forlaterally displacing material lying on the ground and of the type whichcomprises rake wheels.

This application is a division of application Serial No. 587,639, filedMay 28, 1956, and now Patent No. 2,926,476.

It is known to provide said implements with cranks, whereon the rakewheels are mounted. It is an object of the invention, however, toprovide an implement, in which the rake wheels are mounted on the framein a simple manner and wherein the rake wheels are flexible to adaptthemselves to irregularities of the ground, the frame also being of avery simple construction.

In accordance with the invention there is provided an implement forlaterally displacing mown grass or like material lying on the ground,the implement being of the kind comprising a row of rake wheels mountedon one side of a main frame beam, each rake wheel being positioned so asto lie obliquely to the intended direc tion of travel of the implement,and each being adapted to be rotated by virtue of its contact with theground, said implement further comprising a secondary frame beamdisposed on the side of the row of rake wheels opposite that on whichthe main frame beam is disposed, such secondary frame being held inspaced relation to said main frame beam with the aid of twointerconnecting members, each of which extends through the hub of anassociated rake wheel and constitutes an axle for the rotary support ofsuch rake wheel.

For a better understanding of the invention and to show how the same maybe carried into effect, reference will now be made by way of example tothe accompanying drawing in which the sole FIGURE is a plan view of animplement of the kind to which the invention has been applied. I

As shown in the drawing, the implement includes a main frame beam 1 and,mounted on one side of the frame beam, a row of rake wheels 2, 3, 4 and5. 0n the other side of the row of rake wheels there is a secondaryframe beam 6 extending transversely to the intended direction of travelof the implement and held in spaced relation to the main frame beam 1 byinterconnecting members in the form of axles 7 and 8. The two axles 7and 8 have the hubs 9 and 10 of the rake wheels 3 and 4 freely rotatablymounted thereon. Prolongations 11 and 12 of the axles 7 and 8 extendthrough the hubs 9 and 10 and are connected to the frame beam 1. Theconnections between the prolongations 11 and 12 and the frame beam 1 arestrengthened by tie-bars T. Axles 14 and 16, parallel to the axles 7 and8, are attached to the frame beam 1 at the ends 13 and 15 respectively.The axles 14 and 16 extend through the hubs 17 and 18 of the rake wheels2 and 5, so that the rake The hubs 17, 9, 10 and 18 of the rake wheels2, 3, 4 and 5 respectively are substantially aligned.

The frame beam 6 is connected to a drawbar in the form of a shaft 19which is rotatably but not slidably supported in a tube 20. The shaft 19can be locked in the tube 20 in the position shown, by a locking pin 21,there being, however, sufficient play to allow the shaft 19 to turnthrough an angle of about 10 in either directionaway from theillustrated position.

As shown in the drawing, the implement is coupled to a tractor 22 havingat its rear end three links 23, 24 and 25 of a three-point liftingdevice 26. The lifting device 26 carries a fastening device 27 which iscomposed of two obliquely upwardly extending bars 28 and 29 rigidlyconnected to respective ends of an arcuate strip 30 and to two strips 31and 32 which are themselves rigidly connected to a plate 33. The plate33 carries a pin 34 about which a lu g 35 is hingeable, the lug carryingthe substantially horizontal tube 20. The for-ward end of the tube isprovided with a locking device 36 which, when inoperative, can slidealong the strip 30 when the tube 20 turns about the pin 34. The device36 can be locked in one of a number of places on the strip 30 so as toprevent movement of the tube 20 about the pin 34.

In the drawing, the implement is shown occupying a position in which itwill act as a swath turner. When the implement is raised a sufiicientheight from the ground with the aid of the lifting device 26 of thetractor 22 and the pin 21 is temporarily removed, the shaft 19 can beturned through 180 in the tube 20. If the implement is then lowered sothat the rake wheels contact the ground, the implement occupies aposition in which it can act as a side-delivery rake.

What we claim is:

1. An implement having a normal direction of travel I and adapted forlaterally displacing material lying on the wheels are freely rotatableupon their respective axles.

'ground, said implement comprising a main frame beam,

rake wheels aligned in a row on one side of said main frame beam, eachsaid wheel being positioned obliquely relative to said direction oftravel, a secondary frame beam spaced from said main frame beam, saidrake wheels being positioned between said frame beams, interconnectingmembers connecting said frame beams and having fixed relationshiptherewith, each said interconnecting member extending through andconstituting a fixed ax-le for one of said rake wheels, and fixed axleson said main frame beam and supporting the remainder of said rakewheels, said rake wheels being freely rotatable on their respectiveaxles.

2. An implement as claimed in claim 1 comprising a drawbar connected tosaid secondary frame beam.
